This study aims to generalize the following result of McDonald and Siegel (1986) on optimal investment: it is optimal for an investor to invest when project cash flows exceed a certain threshold. This study presents other results that refine or extend this one by integrating timing flexibility...

Using the Credit Rating Agency Reform Act of 2006, we examine the credibility of mandatory disclosure by credit rating agencies (CRAs) on managerial learning from stock prices. We find an increase in investment-price sensitivity for firms affected by the Act. Consistent with managers relying...

We develop a new dynamic continuous-time model of optimal consumption and investment to include independent stochastic labor income. We reduce the problem of solving the Bellman equation to a problem of solving an integral equation. We then explicitly characterize the optimal consumption and...

We develop an analytically tractable model of optimal financing policies for a risk averse decision maker who is exposed to climate risk causing a significant disruption to capital stock accumulation. We quantitatively identify certain thresholds of cash-capital ratio explicitly characterizing...

We study the impact of income disaster-which can be triggered by various reasons such as pandemics and technological disruption-on Friedman's permanent income hypothesis. Although the hypothesis is still retained, our general equilibrium model offers two insights. First, with income disaster the...
